wiring the Huajiang yl6000 inverter to mach 3

1) Acquire a 5 or 6 conductor wire cable of generous length to fit between your Mach30 controller and your VFD (Variable Frequency Drive). The wire gauge should be somewhere between 18GA and 22GA. Maximum current draw will be under 20 milliamps. Cable may also be shielded and/or twisted pairs. 2) Wire #1 from controller ground to VFD XGND (DC ground) 4) Wire #2 from controller output defined as (MACH3 output#2) to VFD FWD input Note This will give you the ability to start and top the spindle. 5) Wire #3 from controller analog ground (Speed circuit) to VFD GND. 6) Wire #4 from controller analog speed output to VFD VI1 (Speed control voltage). 7) Wire #5 from controller Analog speed 10V or 12V input to VFD 10V or VFD 13V output. (Analog supply voltage). 8) Program the VFD to accept external start and stop control with front panel STOP. 9) Program the VFD to accept external analog speed control for zero to ten volts input. The above wiring will allow you to start and stop the spindle, and set the spindle speed. You will have control both from G-Code and Mach3 front panel control, including manual On/OFF and percentage control. Note: Modbus control is very difficult and fussy to set up, and you lose mach3 front panel manual control.
